President Barack Obama's energy and climate-change czar seemed to like what she saw at a green-jobs training program Friday in West Oakland.
"It is so impressive what you all are doing," Carol Browner said while visiting the Cypress Mandela Training Center on Poplar Street, noting this was her first solo field trip in her capacity as head of the White House Office of Energy and Climate Change"

It is widely recognised that humans are their own worst enemies when it comes to global warming.
But the latest research from Nasa suggests laws created to preserve the environment are causing much of the damage.
Legislation to improve air quality and cut acid rain has accounted for a shocking half of Arctic warming over the past three decades, the space agency reports.

Elephant seals equipped with electronic tags and robotic mini submarines using sonar were just two projects during the International Polar Year (IPY) that aimed to investigate the effects of global warming in polar regions.

The global warming situation has become so dire that Barack Obama's chief scientific adviser has raised with the president the possibility of massive-scale technological fixes to alter the climate known as 'geo-engineering'.
John Holdren, who is a member of the president's cabinet, said today the drastic measures should not be "off the table" in discussions on how best to tackle climate change. While his office insisted that he was not proposing a dramatic switch in policy, Holdren said geo-engineering could not be ruled out.
